To all whom t may concern,

Be it known that NICHOLAS FEINEN, a citizen of the United States, residing at Buffalo, inthe county of Erie, and State of New York, have invented new and use ful *Improvements in Snap Switches, of which'v the following is a specification.

rlhis invention relates to improvements in electrical switches of the snap type in which the switch is opened and closed by rotating a handle member, the general object of the invention being to provide indicating means vassociated with the handle member for indicating the off7-and on positions of the switch.

Another object simplifythe construction so that the switch can be'manufactured to sell at low cost and to reduce the number of parts so that the switchlifwill be of simple operation and not liable to get out of order.

This invention also consists in certain other features ofconstruction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying ldrawings and specifically pointed out in the appended claims. 7

In describing my invention in detail, reference will be had to lthe accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which 2- Figure 1 is a plan view of the invention.

Figure Q is a central sectional view.

Figure 3 isa view showing certain parts of the switch unassembled.

In these views 1 indicates the insulated base of the switch and Q the enclosing' casing for. the switch parts. rllhe two contacts 3 are secured to the base by the screws 4 and these contacts include the usual binding screws for holding the terminal wires of the circuit. An opening is formed in the center of the base 1 and a screw threaded sleeve 5 passes through said opening and throughI an opening in the casing. This sleeve is connected. with the base by the nuts 6 which engage the top and bottom faces of the base. The s ring switch blade 7 has a perforated cupsliaped central part whichi litsover the sleeve and a washer 9 on the sleeve has a lforked ear 10which engages part of the blade. This washer is adjusted on the sleeve by the nut 11. A sprin 13 is located in the cupshaped part of t e blade and bears against of the invention lis tov the 4bottom of said cup-shaped part and the washer so that the blade is frictionally held against the contacts. A shaft 14 passes through the sleeve with its square lower end engaging the square hole in a bracket 15 which is supported on the lower face of the base by the screws 4, thus the shaft 14 is held against rotary movement. A disc 16 is connected with the upper end of the shaft and this disc carries suitable indicia 17, such as the words fon and ott A cap 18 fits p over the disc and said capi is provided with an opening 19 through which the words on the' disc will appear. A plug 20 of insulating material fits in the cap and is held therein by the screw 21. This plug includes a screw threaded bushing 22 which engages the ,upper end of the screw threaded sleeve and the lower end of whichy bears against nut 17.

- lt will thus be seen that the switch blade can be moved by rota/lng the cap by the lingers as this movement of thev cap will cause the 'sleeve and its attached parts to move and the blade will be moved.' by its engagement p with the forked ear 10 of the washer 9. As the disc 16 is held against rotary movement iby reason of the fact that the shaft 14 has a square end engaging a square hole in bracket 15, the words on said disc will appear through opening 19 as cap 18 is rotated. The drawings show the parts arranged to be moved a quarter turn to cause the switch blade Ito travel from ofi position to on position and vice versa.

lt is thought from the foregoing descrip'- tion that the advantages and novel features of my invention. will be readil apparent.

l desire it to be understoo make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What-l claim is V1. A switch of the class described comprising la base, contacts thereon, av hollow member rotatably supnnrted by the base, a switch blade connected with the hollow member and engaging thecontacts, a cap member connected with the hollow member and having an opening' therein, a stationary member passing through the hollow shaft and an indicator' disc connectedwith theV stational-y member and located within the cap.

2. A switch of the class described comprising a hase, contacts thereon, a hollow that l imayy screw threadedmember rosatably supported disc,14 a plug connected with the cap membe by the base, a stationary shaft passing and having a, part connected with the hol- 10 through the hollow member, said staionary low member, av switch blade and means for.
